Shore-access deep lake dive with a steep slope.
Challière, Lac du Bourget is a shore-access freshwater dive on the lake shore. The entry is from the beach or roadside, and the slope drops fast from the shallow edge into deep water, so the site suits confirmed cold-water divers rather than casual beginners. Expect variable visibility, cold water, and fish life such as char, perch, pike, carp, and catfish.
